Abstract

The invention relates to a sensor element for determining different gas contents in a measurement gas (12), in particular in an exhaust gas of an internal combustion engine, said sensor element comprising an oxygen-measuring probe (2) for determining an oxygen content in the measurement gas (12), a first mixed-potential electrode (3) and a second mixed-potential electrode (4), wherein the first and second mixed-potential electrodes (3, 4) can be used to determine at least one further content of another gas in the measurement gas.
